IN WIN Commander 1200W Power Supply Review

Electrical Safety Test Class 1
Manufacturer/Model	Pass/Fail
IN WIN Commander 1200W	Pass

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and all four 12V lines in turn. The power supply did shut down, and once the short was removed and the unit switched off for at least one second, resumed normal operation. Although listed here at the beginning of the testing section, I tend to leave this test until the very end, in case it doesn't quite go to plan.

Total Power Supply Loading			1193W

 

The 12V1 and 12V2 rails are rated for 20A maximium so technically speaking they are overloaded. It's not going to prove anything, most power supplies will easily cope with 10% extra, so don't read too much into it. The IN WIN Commander 1200W performed very well in this section and all the DC rails remained at optimum levels even at almost 100% loading.
